Back To The Future - A R/C Transmitter for Planes That Doesn't Need Power!
In the movie "Back To The Future" at 21:11 Min. into the movie, when the doctor is controlling the DeLorean with a Futaba AIRPLANE Remote Control Transmitter, you can clearly see that the transmitter is off, and the battery level is at zero.
I have a similar model Futaba controller, and I can tell you there isn't enough power in the battery pack at 50% to run the thing, let alone 0%, even in an earlier scene (20:32) where the power LED is on, and the switch is in the "On" position, the gauge still reads 0%, and the LCD at the bottom is blank (the LED was probably filled in later when noticed).
Other things wrong with this scene:
Controls are used improperly: E.G. the right Y axis was used for the throttle, when it's supposed to be the left Y axis; Incorrect cross control (when the car is facing you, you push left to make the car go right).
Thanks for your time,
Hope this helps,
